1 degree wing angle removal

I asked John about TIG welding the holes closed and redrilling. He did not like that idea. The sleeve solution sounds like it has merit.

There was a lengthy discussion relating to this many years ago - long before the wing sweep idea first surfaced. Basically the conclusion was that forces on the front spar during flight were compressive. Meaning aerodynamic forces in flight tended to move the wing forward. The comment was made that if the Clevis bolt somehow fell out, the wing would not fold back. I mention this only to suggest that any failure mode from a modification, according to those conclusions, would be a slippage back to the wing sweep position which would create a CG issue rather than a catastrophic wing failure. I can't even imagine that happening with a closely fitted cuff, Hysol, and rivets.
